When running the ioat_rawdev_autotest, the ring size was initially required
to be 0. This prevented the test being run multiple times, as the ring size
is modified to a non-zero value when running the first test.
A global variable is now used to track the expected ring size, and is used
in the initial value check. This enables the test to be run more than
once.
